I had my retics get nipped a few times during feeding ( feed the gar first floating food ect then feed sinking)
Also my big pair of tropical gar have killed and iir eaten small rays before at a previous owners tank, in my own they have not killed a tank-mates yet.
atm I do not keep gar/ray together but I do believe space and feeding routine can play a significant role in them working. Granted there are some gar that are simply that aggressive.
imo gators should never be housed w/ rays unless in VERY large enclosures ( ie outdoor pools/ponds ect) Tropicals and Cubans... then the smaller species.
